Two days after the film opened, two men poured gasoline over a ticket booth on the Brooklyn subway and set it alight in an incident similar to the one depicted in the film. The booth attendant was burned and later died of his injuries. Consequently, New York City subway workers called for a boycott of the film and the removal of all the posters from every station. Senator Bob Dole quickly came out in support of them. Columbia Pictures refused to bow to their demands. As a result of the controversy, Chris Cooper, who portrayed the pyromaniac, would admit regretting participating in the film.
This boasts the distinction of having one of the longest sets ever constructed for a film. At over three thousand feet long, twenty feet high, and four railway tracks wide, the set was roughly the same size as two Empire State buildings lying side by side. The original plan was to film in the real New York City subway, but the logistics proved to be too problematic.
Twelve New York City subway cars were shipped over to Los Angeles to the film set. They were converted to run on propane so that the rails on the film set did not need to be electrified, a potential health hazard for all of the crew.
The prop train used for the money train was an actual retired New York City subway train that was destined to be scrapped. After the film was completed, it was donated to the New York City Transit Authority, and currently resides in the Coney Island Rapid Transit Yard.
Most of the subway scenes were filmed on a four thousand-foot-long (1.2 km) set built to resemble a typical four-track New York City subway trunkline. It included three stations, all of which were built as local stops with the platforms on the outside of the outer tracks. Included were I-beams between each track, spaced five feet apart just as they are in New York City. The ceiling, however, was much higher than on any actual New York City subway line.
